To all ii /10m it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in East Haven, county of New Haven, and State of Connecticut, have invented certain new and useful Improvements in Rabbeted Lock Fronts and Strikes, of which the following is a full, clear, and exe This invention relates to form of lock front and strike doors and other parts, and the ject of the invention is to front and strike which may economically manufactured and plied to the rabbeted portions spective: supporting members.

By my improved construction the front and strike are of such simple form as to be easily and inexpensively produced and they may be applied to the rabbeted portions of their supporting members without cutting or mortising the latter to the considerable extent necessary in the prior constructions with which I am familiar.-

To these and other ends the invention consists in the novel features and combinations of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a fragmentary View of the meeting ortions of two hinged doors or other mem ers equipped with my an improved for rabbeted primary obrovide a lock chea ly and rea ily apof their re- "t description.

posed by the stop bead or ledge 15 of the door 10 while the stop bead or ledge 16 of improvements, showing the doors in their closed position. Fig. 2 is a section on line 22 of Fig. 1, Figs. 3 and 4 are enlarged elevations of the strike and lock front mounted in their respective supporting members. Fig. 5 is a detail perspective view of the strike. Fig. 6 is a fragmentary perspective view of the lock, and Fig. 7 is a detail section on line T-7 of Fig. 4.

Referring to the drawings. 10 indicates a member or part equipped with a mortise lock 11. and 12 indicates a member or part equipped with a strike 13 cooperating with the lock 11. The character of the members 10, 12 is more or less immaterial, but it will be assumed for the purposes of description that each is a swinging door adapted to be locked at its free edge, when closed to the meeting edge of the other door. The meeting edges of the doors 10, 12 are rabbeted in the manner shown in Figs. 2. 3 and 4 in order to shut off the crack between the doors, the rabbet 14 of the door 12 being opthe door 12 is similarly opposed by the rabbet 17 of the door 10. he interior mechanism of the lock 11 may be of any preferred type but in the embodiment illustrated the lock comprises a dead bolt 18, and a latch bolt 19 operable by means of a knob 20. The lock 11 is fitted in a mortise 28 in the rabbeted edge of the door 10 and the bolts 18, 19 pass through a front or face plate 21 of novel form which is applied to said rabbeted edge in the manner now to be described.

The front of the face plate lies in. a single vertical plane and at one side it is mortised in the ledge or bead 15 in the customary way, for which purpose said ledge or head is cut away at 22 to receive say approximately half of the face plate. At the opposite side the face plate is provided with a. rearward extension 23 extended substantially at right angles to the main portion thereof and parallel to and opposing a portionof the side wall of the case, as shown in Figs. 2

At the rear edge of the main vertically directed portion of this flange 23, the latter is abutted directly against the adjacent face of the rabbet- 17. with which it makes a neat joint without mortising, the top and bottom portions 24 of said flange being curved over on an easy curve to meet the other wall of the rabbet in the same way. Hence it will be understood that only a part of the face plate is mortised in the stopbead. while the other part extends out over the rabbet. into which it projects and in which it may be accurately fitted without mortising. The rear edge of the flange 23 is abutted throughout its length against the transverse wall of the rabbet 17 .Z. that wall which is substantially perpendicular to the plane of the door, while at its upper and lower extremities the said flange is provided with edge portions joined with the main body portion of the flange by easy curves and lying parallel to the plane of the door. in abutment with the other wall 2'. e. the longitudinal wall, of the rabbet. These edge portions. which are spaced above and below the top and bottom walls respectively of the lock case. will preferably overhang the case to such an extent that they are alined with the central plane thereof. The face plate 21 may be secured to the case of the lock 11 in any of the ways well understood in the art. The lock is secured to the .door by means of the usual screws 26 which pass from the ends of the face plate through in the usual manner except that it is provided with a perpendicularly disposed side wall or stop flange 30 which is mortised into the bead 16 and is. shaped to receive and conform to the flange 23 of the look. It is preferred to have the upper and lower portions of the flange 23 extend approximately half way across the width. of the face plate, and similarly the inturned upper and lower portions 31 of the strike will preferably extend about half way across the main portion of the latter, as shown in Figs. 3 and 5. The strike is preferably secured to its supporting part by means of two screws 32 at each end, one passing into the mortise in the transverse wall of the rabbet 14 and the other passing into the transverse wall of the mortise in the bead 16. Aside from the provision of the stop flange 30 and its relation tothe supporting member, the strike is of the usual form and its other features need not be described "in' detail.

In addition to the advantages already recited, my improved construction has the further advantage that the same form of lock case may be used for right and left-hand doors, it being merely necessary to select and apply to the case a rabbeted front of the desired kind. In other words, a rabbeted right or left-hand front may be applied to the ordinary lock case as manufactured for the customary flat front. Heretofore, it has always been necessary, so far as I am aware, to have one side of the case longer than the other when a rabbeted front of one hand is used, and to employ sides havin a reversed arrangement when a rabbeted nt of the other hand is used.

Without limiting myself to the construction shown I claim:

1. The combination with a lock having a case, and a face plate extending laterally beyond the case at one side, of a flange extending from the last named side of said face plate alongside and parallel to one wall of the lock case to a point back of the front edge of such wall; substantially as described.

4.. The combination with a mortise lock 7 having a case and a face plate, of a flange extending rearwardly from one edge of the face plate alongside and substantially parallel to one wall of the case, said flange being extended over and spaced from the case at the top and bottom of the latter; substantially as described.

9. The combination with a member having a rabbeted edge, of a lock mortised in said member, a face plate for said lock, one side portion of which is mortised in the bead or ledge portion of said rabbeted edge, and. a flange on the opposite side of said face late extended longitudinally and transverse y to meet both walls of the rabbet; substantially as described.
